Info sui prodotti "DNM-831I-100V-50A Voltage Attenuator and Current Transformer, ±100 V / ±50 A"
The DNM-831I-100V-50A CR combines one high-voltage channel and one high-current channel in a single DIN-rail module. Inputs of up to ±100 VDC and ±50 A are attenuated to a ±10 V output, so they can be read by analog input modules that expect a standard voltage signal.
Each input is isolated from its output and from the other channel, with 3000 VDC isolation between modules and between channels. This helps keep noise from the high-voltage and high-current circuits out of the measurement path. The current input uses the supplied clip-type current transformer with a 21 mm aperture and a 1.5 m lead.
The order includes the CA-040415 cable and the ASO-0002 current transformer. The module is housed in metal, operates from +10 VDC to +30 VDC and is rated for -25 ~ +75 °C. It carries CE, UKCA, FCC, RoHS and WEEE marks.
Applications
- High-voltage measurement with analog input modules
- High-current measurement with analog input modules
- Monitoring of AC and DC voltage and current signals in industrial control panels
